Hello again everyone

I've come across the following report in the Newcastle Journal, June 2nd 1945:

Shields man gets D.F.M.
For his services in the Indian Ocean on October 12 last year, when he took part in the sinking of an enemy submarine, Flight Sergt. William Bumphery (22), of Berkley Street, South Shields, has been awarded the D.F.M. Bumphery volunteered for the R.A.F. in 1941 and was formerly an apprenctice gardener.

So, a Google search brings up a bit fat zero for 'Bumphery' and DFM. Air 78/24 has a William Albert Bumphrey, service No. 1495791, with a handwritten note saying he is now called Humphrey.

A quick search on FreeBMD has a William A. Bumfrey, registered South Shields, December 1921, which almost fits the details.

His service number is amongst those allocated at Padgate, April 1941, so that fits too. Can't find anything on the LG website for 1495791 and Humphrey/Bumphrey/Bumphery/Bumfrey etc though.

Any helpful suggestions most gratefully received - I'm missing something obvious here, I know!
